A method includes selecting, in a radiographic exposure unit, a direct radiographic panel as an active panel for a forthcoming radiographic exposure, activating a gravity sensor installed on the direct radiographic panel, and activating by the activated gravity sensor a processor installed on the direct radiographic panel. As a result of a communication from the processor with a radiographic work station over a network, the activated direct radiographic panel is retained as the active direct radiographic panel for the forthcoming radiographic exposure.
